Hyperliquid’s SPACEX-USDH perpetual contract, which tracks market bets on SpaceX’s valuation, suffered a sharp flash crash on Thursday afternoon. The contract fell from an opening price of $2,277 to a low of $1,254 in a single 30-minute stretch, a drop of nearly 45%, before rebounding to around $2,169. According to Hyperliquid data, the move liquidated 405 users across 1,393 positions, erasing about $1.51 million in notional value.
Thin trading met a sudden burst of volume
The scale of the move stands out even more when set against the contract’s usual activity. Over the previous 24 hours, total trading volume was only $4.87 million, while open interest stayed below $2.9 million. Then a single candle appeared to absorb what was likely a large share of that daily turnover, exposing how little market depth was available when heavy selling hit.
Liquidation data points to a retail-dominated market. The median liquidated position carried just $31 in margin, suggesting many traders were using roughly 3x leverage with very little room for error. In a contract with limited liquidity, that setup can turn a fast move into a cascade.
A synthetic bet on SpaceX, not ownership of shares
The SPACEX-USDH product is a crypto perpetual contract tied to SpaceX’s market valuation. Because SpaceX is still private, traders cannot buy its stock directly ahead of the company’s expected IPO. Hyperliquid’s contract was built as a synthetic way to speculate on what the company might be worth.
That exposure does not represent actual shares in Elon Musk’s rocket company, and it does not give holders any shareholder rights. It is a derivatives market built around price expectations rather than equity ownership.
No public spot benchmark to anchor the contract
Unlike perpetual futures tied to Bitcoin or Ethereum, the SpaceX-linked contract has no deep public spot market beneath it. SpaceX shares change hands only in private secondary markets restricted to accredited investors, leaving no broadly available benchmark for traders to reference in real time.
Even after the selloff, the contract still showed a premium. At settlement, the mark price was $2,132, more than $220 above the oracle price of $1,908. The source material also said SpaceX is targeting an IPO in June.
